8.关于日期格式 k((_~<$2K
v:s~Y
日期格式设定 @/B&R^aVZ
DataFormatString="{0:yyyy-MM-dd}" b.;F)(

我觉得应该在itembound事件中 %3'80u6BCJ
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) o!\Vk~Vi&

9.获取错误信息并到指定页面 0j_`7<,:
a|lcOU
不要使用Response.Redirect,而应该使用Server.Transfer ewY+a ,t
U6n%rdXJ=
e.g vSPkm)O0)
// in global.asax a:v&pj+|<
protected void Application_Error(Object sender, EventArgs e) { %k5^n0|*
if (Server.GetLastError() is HttpUnhandledException) <|s|6C
Server.Transfer("MyErrorPage.aspx"); vMj"%
K`PF|=z
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) nwHi3ojD:
} Xxp<qIEm
3%!d&j>v
Redirect会导致post-back的产生从而丢失了错误信息,所以页面导向应该直接在服务器端执行,这样就可以在错误处理页面得到出错信息并进行相应的处理 @ 5|F:J
